Mr McGarry’s parents, Sean and Helen, and two sisters, Louise May and Joanne McGoran, set up a Just Giving page in a bid to raise £50,000 needed for his life-saving treatment.

A statement on the family’s fundraising page said: "Peter is continuing to improve every day. His neurosurgeon says that Peter's post-operative condition and prognosis is in the top 5% of patients having this type of haemorrhage.

"His progress over the past few weeks has been amazing.

"Thanks to his fighting spirit but obviously a huge amount is down to the care he has been able to receive due to the donations made. All the prayers and positive thoughts have made the difference. Thank you all x"

The news follows last week's update that said surgery had gone well and that doctors were pleased with how things went.

"They successfully secured the aneurysm although surgery took longer than expected.

"He has been awake today and talking and able to remember so much. The doctors are all very pleased with how everything has gone so far," the update said.

The family had to spend some of the funds raised to move Peter to a bigger hospital since he was initially placed in a local hospital not equipped to deal with his injuries and described as ‘barbaric’ by the founder of Guatemala Medical Travel.

Since launching the appeal, the family have managed to raise over £48,000 and have been flooded with supportive messages from friends and extended family.

A post from a friend on the Just Giving fundraising page describes Peter as “a rare, beautiful man who will surprise us all by how well he gets through this”.

Louise May said: “We’re overwhelmed with the support we’ve received from family and friends, and even total strangers.”

Peter has been living in Guatemala for two years, and has not seen his family since moving over. The hope is that if his surgery is successful, he will be able to return to Ireland for further treatment.

“Of course we missed him anyway; for this to happen while he’s away is so difficult,” Louise May said.
